T 0 all whom it may concern:

Be it known that ROYAL E. lilAnriit. citizen of the United States of America; residing at Mansfield, in the county of Richland and State of Ohio, has invented certain new and useful Improvements in Means for liemovably Clamping Vzglves to Pneumatic Tubes or the like, of which the following is a specification.

This invention. relates for removably clamping matic tire tubes.

One of the'objects of the present invention is to provide means for rhanging and removing the valve from the inner tube of a pneumatic tire and replacing same with another valve or in other words providing means for the interchangeability of pneuinatic valves on inner tubes for tires or the ike;

to improvements valves to pneu A further object is to provide means for inserting a valve and. attaching same to an inner tube or the like without mutilating same or weakening the tube on account of forming large apertures or openings therein.

Another object is to provide means for frictionally clamping the tube between an elongated valve member and a separable clamping member to prevent the escape of air with or without the use of extra patches or strips.

A further object is to provide means for inserting the valve mechanism and its elongated base from the exterior of the inner tube or the like.

Another object is to provide a. clamping mechanism that contacts with a large area of the inner tube so that the valve cannot be broken away or wrenched from the tube as is the case where the base of the flange or valve is made round and only contacts with a slight area of the tube.

Having these and other objects in view the invention is illustrated in conventional form in the figures shown.

Figure l is a side elevation of the valve in assembled form showing same partly in section clamped to the inner tube.

Figure 2 is an end elevation of the valve and clamping mechanism, as shown in Fig. 2.

Figure 3, is a plan view showing the serrated olamping member and lock nuts.

Figure 4 shows a plan view of a. portion of the inner tube showing apertures therein with a slit in the tube intersecting said apertures.

' In the drawing reference numeral 1, represents the body of a conventional type of a pneumatic valve mechanism. An elongated portion 2 having its upper surface 3, serrated is made integral with the lower portion or base of the valve body' 1. The elongated portion 2, is also provided with an exteriorly threaded boss 4 A separable clamping member having its lower surface serrated is providedwith its ends 7 and 8 extending upward in angular relation to the tube. The separable member 5 is provided with different size apertures 9 and 10, which fit over the body 1 of the valve and boss 4. The inner tube 11 is interposed between. the elongated portion 2 of the lower portion or base of the valve and the separable clamping member 5. w

The clamping member and the base of the valve are held in close frictional contact with the tube 11 through themedium of the lock nuts 12 and 13, thereby preventing the escape of air from the inner tube due to the large area of the clamping members which are brought in frictional contact under pressure with the inner tube or the like.

To insert, remove, or replace a valve into another tube as described, apertures of different sizes are provided in the tube of small diameter,'which are disposed in alinement with each other and connected or intersected through the medium of a slit 141-.

When it is desired to insert or remove the valve mechanism to or from the inner tube the base is turned topresent its narrow side toward the apertures and slit. The base is then pressed inward against the tube and the portion of the tire provided with the slit bent inwardly permitting the base and lower portion of the valve members to ex tend within the interior of the tire and then turned at right angles to the position that it was inserted in, as shown in Fig. 1.

The separable clamping member 5 is assembled on the valve body and the lock nuts tightened clamping an inner tube or the like therebetween.

The same operation in reverse order is performed in withdrawing the clamping members from the tube, when it is desired to assemble and connect same to another tube or the like.

It will be ObViOHS l q b11056 skilled in the art that in the construction of valve clamping mechanism as herein described, that the valve can be changed from an old or worn out inner tube to a new inner tube, Without the loss thereof the further fact that the valve clamping mechanism can be inserted easily and with convenience from the outside of the inner tube making it unnecessary to place the valve in the inner tube while it is being spliced in its manufacture. Attention is further called to the fact that by'the method described herein of inserting the valve from the outside that it is only necessary to out small apertures and connect same by a slit in the tube as described here- 111 the method of connecting a clamping means for mounting a valve can be used on rubber articles or the like of different kinds without deviating from the principle of the invention herein described.

The showing herein made in the drawing and described in the specification is only conventional as immaterial changes may be made within the scope of the present invention without departing from the spirit thereof.

I claim:

1. Means for clamping a valve to pneumatic tubes, comprising a separable elongated member, a valve body having an elongated member and a threaded boss and means to clamp the tube therebetween.

2. A valve clamping mechanism comprising elongated members in combination with an inner tube, said tube being provided with apertures and an intersecting slit which provides means for inserting or removing said valve mechanism. a

3. A valve clamping mechanism in com- I Attention is further called to the fact that nism adapted to fit over the boss and valve body, and means for clamping said elongated base and separable clamping member against an interposed portion of a tube.

5. A valve clamping mechanism for pneumatic tubes comprising a valve body having an elongated base and a threaded boss, a separable elongated clamping mechanism adapted to fit over the boss valve body, means for clamping said elongated base and separable clamping member against an interposed portion of an inner tube and means provided in the inner tube to admit of the inserting of the elongated base of the valve member without mutilating or tearing the inner tube, as and for the purpose described.

6. In a clamping mechanism for pneumatic tubes, comprising a valve member having an elongated base and threaded boss; said inner tube being provided with apertures spaced apart from each other and intersected by a slit whereby the valve member can be inserted from the outside into the inner tube and a clamping means adapted to clamp a portion of an interposed tube therebetween, as and for the purpose described.

In testimony whereof I afiix my signature.

ROYAL E. MARTIN.
